Description

Technical Field

[0001] The present application relates to the technical field of kitchen appliances, and in particular to a range hood. Background Art

[0002] Range hoods are common kitchen appliances in daily life, used to remove fumes generated during cooking in the kitchen. In order to improve the fume removal effect, the side-suction range hood in the related art includes a shell and a smoke collecting plate located on the front side of the shell. An air inlet is provided on the smoke collecting plate, and the range hood also includes a main smoke baffle that can rotate relative to the shell to open or close the air inlet. Side smoke baffles driven by the main smoke baffle are respectively provided on the left and right sides of the shell. The side smoke baffles are divided into a first smoke baffle and a second smoke baffle that can overlap and unfold with each other. When the range hood is working to smoke, the main smoke baffle is driven to rotate and open, thereby driving the first smoke baffle and the second smoke baffle to fully unfold. Under the cooperation of the first smoke baffle, the second smoke baffle and the main smoke baffle, a smoke collecting effect is achieved.

[0003] When the internal space of the housing is small, in order to allow the first smoke shield and the second smoke shield to be accommodated in the narrow space after being folded, the maximum width of the first smoke shield and the second smoke shield needs to be reduced accordingly so that they can be accommodated in the housing after being folded. However, when the first smoke shield and the second smoke shield are fully unfolded with the main smoke shield rotating and opening, the smoke-collecting area enclosed by the first smoke shield and the second smoke shield is reduced accordingly, which will reduce the smoke-collecting effect.

[0035] In order to make the above-mentioned purposes, features and advantages of the present application more obvious and easy to understand, the specific implementation methods of the present application are described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the present application. However, the present application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the present application, so the present application is not limited by the specific embodiments disclosed below.

[0036] See also Figures 1 to 4 , Figure 1 A structural diagram of a range hood according to an embodiment of the present application is shown. Figure 2 Shows Figure 1 Enlarged structural diagram at A. Figure 3 Shows Figure 2 Another perspective structural diagram of the structure shown. Figure 4It is shown that the smoke collecting plate 22 of one embodiment of the present application is in a state of closing the air inlet 21. An embodiment of the present application provides a range hood, comprising a smoke collecting hood 20 provided with an upper air inlet 21, a smoke collecting plate 22 for closing or opening the air inlet 21 rotatably provided on the upper part of the smoke collecting hood 20, and a side wing smoke collecting assembly 10 for collecting smoke provided on the left and right sides of the air inlet 21. Specifically, the side wing smoke collecting assembly 10 comprises: a first smoke baffle 11, a second smoke baffle 12 and a movable plate 13. The first smoke baffle 11 is fixedly mounted inside the smoke collecting hood 20. The second smoke baffle 12 is used to be connected to the smoke collecting plate 22 and can rotate synchronously driven by the rotation of the smoke collecting plate 22. The movable plate 13 can be set as one; in addition, it can be set as a plurality of them and connected in sequence, and any two adjacent ones can be stacked on each other or spread out on each other. All movable plates 13 are connected between the first smoke baffle 11 and the second smoke baffle 12 . The movable plates 13 close to the first smoke baffle 11 and the second smoke baffle 12 can slide with the first smoke baffle 11 and the second smoke baffle 12 respectively, and can rotate synchronously with the rotation of the second smoke baffle 12 .

[0037] When the first smoke baffle 11, all the movable plates 13 and the second smoke baffle 12 are in the folded position, the first smoke baffle 11, all the movable plates 13 and the second smoke baffle 12 are stacked together and are all located inside the smoke collecting hood 20. Figure 4 When the first smoke baffle 11, all the movable plates 13 and the second smoke baffle 12 are in the deployed position, the first smoke baffle 11, at least one movable plate 13 and the second smoke baffle 12 are deployed with each other, and at least one movable plate 13 and the second smoke baffle 12 move to the outside of the smoke hood 20, as shown in FIG. Figures 1 to 3 shown.

[0038] In some embodiments, the number of movable panels 13 includes but is not limited to one, two, three or more, and is flexibly adjusted and set according to actual needs. Among them, when the first smoke baffle 11, the second smoke baffle 12 and all the movable panels 13 are fully unfolded, the angle a formed by the two opposite sides of the overall structure about the rotation center of the smoke collecting plate 22 is certain, and the angle a is, for example, 90°. When the number of movable panels 13 increases, the angle b formed by the two opposite sides of the overall structure about the rotation center of the smoke collecting plate 22 when the first smoke baffle 11, the second smoke baffle 12 and each movable panel 13 are folded together can be reduced, including but not limited to 25° to 35°, so that the space occupied is small and it can be adapted to the inside of the smoke collecting hood 20 installed in a narrow space.

[0039] The above-mentioned range hood includes a side wing smoke collecting assembly. When the side wing smoke collecting assembly is in the folded position, the first smoke baffle, all the movable plates and the second smoke baffle are stacked together and are all located inside the smoke collecting hood, so that the stacked together occupies a small space and can be adapted to the inside of the smoke collecting hood installed in a small space; when the side wing smoke collecting assembly is in the unfolded position, the first smoke baffle, at least one movable plate and the second smoke baffle are unfolded to each other, and at least one movable plate and the second smoke baffle are moved to the outside of the smoke collecting hood, so that when multiple movable plates are used, they can be unfolded simultaneously to increase the smoke collecting area, and the corresponding number of movable plates can also be unfolded according to different smoke collecting needs. Compared with the method in which the range hood in the related art is only provided with the second smoke baffle, the range hood in the present application can adapt to a narrower smoke collecting hood space, and the provision of multiple movable plates can further improve the smoke collecting effect and use flexibility of the range hood.

[0040] In some specific embodiments, the movable plate 13 is provided as one, and the angles formed by the first smoke baffle 11, the second smoke baffle 12, and the two opposite sides of the movable plate 13 about the rotation center of the smoke collecting plate 22 are the same or substantially the same, and substantially the same means that the deviation value is within plus or minus 15%. In this way, when in the folded position, the first smoke baffle 11, the movable plate 13, and the second smoke baffle 12 are stacked together and are all located inside the smoke collecting hood 20. The three stacked together occupy a small space and can be adapted to be installed inside the smoke collecting hood 20 in a narrow space.

[0041] In the related art, in order to increase the service life, the first smoke baffle 11 and the second smoke baffle 12 are usually designed as sheet metal parts. In this way, during the process of rotating and opening the first smoke baffle 11 and the second smoke baffle 12, the first smoke baffle 11 and the second smoke baffle 12 rub against each other, which may easily cause scratches on the board surface and noise defects.

[0042] In some embodiments, the first smoke baffle 11 and the second smoke baffle 12 are both configured as metal parts, including but not limited to sheet metal parts, die castings, stampings or laser milling formed structural parts, etc., and can be processed and formed from various metal materials such as aluminum, copper, iron, etc., and have sufficiently large hardness, thereby improving the support stability.

[0043] In some embodiments, the movable plate 13 includes but is not limited to a non-metallic member, a composite plate with a shock-absorbing layer on the outer surface, or a structural member with a shock-absorbing layer on the outer surface. Among them, the non-metallic member includes but is not limited to a plastic plate, a rubber plate, a resin plate, etc. In addition, the composite plate can be a composite structure formed by two layers, three layers or more layers. In addition, the structural member includes but is not limited to a metal member or a non-metal member, which can be flexibly adjusted and selected according to actual needs.

[0044] In this embodiment, the first baffle plate and the second baffle plate are specifically configured as sheet metal parts, and the movable plate 13 is specifically configured as a plastic part, so that the processing and production can be facilitated and the cost is low.

[0045] Specifically, the movable plate 13 is one and the two opposite sides along the left and right directions of the range hood are respectively slidably matched with the first smoke baffle 11 and the second smoke baffle 12. In this way, it can avoid the hard collision of metal parts to cause scratches on the paint and affect the appearance, and can greatly reduce noise during the opening and closing process; at the same time, when the movable plate 13 is set as a non-metallic part, the bending performance is relatively better, which has the characteristics of low cost and convenient installation and assembly.

[0046] See also Figures 5 to 8 In one embodiment, one of the first smoke shielding plate 11 and the movable plate 13 is provided with a first sliding groove 111, and the other is provided with a first sliding member 131 slidably disposed inside the first sliding groove 111. In addition, one of the second smoke shielding plate 12 and the movable plate 13 is provided with a second sliding groove 121, and the other is provided with a second sliding member 132 slidably disposed inside the second sliding groove 121. In this way, when the side wing smoke collecting assembly 10 is driven by the smoke collecting plate 22 to rotate to the unfolded position (such as Figure 5 and Figure 6 as shown) or folded position (as Figure 7 and Figure 8 During the process of folding, the first sliding member 131 moves along the first sliding groove 111, and the second sliding member 132 moves along the second sliding groove 121, so that the unfolding action and the folding action can be carried out smoothly with good stability.

[0047] See also Figures 5 to 8 In one embodiment, the first sliding groove 111 is configured as an arc groove, the first sliding groove 111 is configured as at least two and arranged in parallel and spaced apart, the first sliding member 131 is configured as at least two, and each first sliding member 131 is correspondingly inserted into each first sliding groove 111; the second sliding groove 121 is configured as an arc groove, the second sliding groove 121 is configured as at least two and arranged in parallel and spaced apart, the second sliding member 132 is configured as at least two, and each second sliding member 132 is correspondingly inserted into each second sliding groove 121. In this way, the unfolding action and the folding action can be carried out smoothly with good stability.

[0048] See also Figures 5 to 8In one embodiment, the first smoke baffle 11 and the second smoke baffle 12 are metal parts, the movable plate 13 is a non-metal part, the first sliding groove 111 is formed on the first smoke baffle 11, the second sliding groove 121 is formed on the second smoke baffle 12, and the first sliding member 131 and the second sliding member 132 are both arranged on the movable plate 13. In this way, on the one hand, since the structural strength of the first smoke baffle 11 and the second smoke baffle 12 is relatively large, the influence of the first sliding groove 111 and the second sliding groove 121 on the structural strength is relatively small; on the other hand, it can prevent the first sliding groove 111 and the second sliding groove 121 from being formed on the movable plate 13, which leads to a decrease in the structural strength of the movable plate 13 made of non-metallic materials. Therefore, the first sliding member 131 and the second sliding member 132 are arranged on the movable plate 13 to increase the structural strength of the movable plate 13, so that it is not easy to be deformed and damaged, and has a longer service life.

[0049] Of course, as some optional solutions, the first sliding groove 111 and the second sliding groove 121 may be formed on the movable plate 13 , the first sliding member 131 may be arranged on the first smoke baffle plate 11 , and the second sliding member 132 may be arranged on the second smoke baffle plate 12 .

[0050] It should be noted that the “first sliding member 131 and the second sliding member 132” can be “part of the movable plate 13”, that is, the “first sliding member 131 and the second sliding member 132” are integrally formed with the “other parts of the movable plate 13”; or they can be an independent component separable from the “other parts of the movable plate 13”, that is, the “first sliding member 131 and the second sliding member 132” can be manufactured independently and then combined with the “other parts of the movable plate 13” into a whole.

[0051] In one embodiment, the first sliding groove 111 passes through two opposite side surfaces of the first smoke baffle 11 along the left-right direction of the range hood, the first sliding member 131 includes a first sliding portion passing through the first sliding groove 111 and a first anti-slip portion connected to the first sliding portion, the first anti-slip portion abuts against and cooperates with a side of the first smoke baffle 11 away from the movable plate 13, and a spacing S1 between opposite sides of the first anti-slip portion along the front-to-back direction of the range hood is greater than a spacing S2 between opposite side walls of the first sliding groove 111 along the front-to-back direction of the range hood. Figure 8 As shown; the second sliding groove 121 passes through the two opposite side surfaces of the second smoke baffle 12 along the left and right directions of the range hood, the second sliding member 132 includes a second sliding portion passing through the second sliding groove 121 and a second anti-slip portion connected to the second sliding portion, the second anti-slip portion and the side of the second smoke baffle 12 away from the movable plate 13 are mutually abutted and matched, and the spacing S3 between the opposite sides of the second anti-slip portion along the front-to-back direction of the range hood is greater than the spacing S4 between the opposite side walls of the second sliding groove 121 along the front-to-back direction of the range hood, as shown Figure 7As shown. In this way, during the unfolding and folding actions, the first sliding part slides along the first sliding groove 111, and the second sliding part slides along the second sliding groove 121, with good movement stability, which can improve stability; in addition, the first anti-slipping part and the side of the first smoke baffle 11 away from the movable plate 13 are mutually abutted and matched, and the spacing S1 of the first anti-slipping part on the opposite sides in the front-to-back direction of the range hood is greater than the spacing S2 of the opposite side walls of the first sliding groove 111, so that the first anti-slipping part and the opposite sides in the front-to-back direction of the range hood are respectively abutted against the side of the first smoke baffle 11 away from the movable plate 13 The two anti-slip portions abut against each other and limit each other, thereby effectively preventing the movable plate 13 and the first smoke baffle 11 from separating from each other; in addition, the second anti-slip portion abuts against and cooperates with the side of the second smoke baffle 12 that is away from the movable plate 13, and the spacing S3 of the second anti-slip portion on the opposite sides along the front-to-back direction of the range hood is greater than the spacing S4 of the opposite side walls of the second sliding groove 121, so that the second anti-slip portion abuts against and limits each other on the opposite sides along the front-to-back direction of the range hood, thereby effectively preventing the movable plate 13 and the second smoke baffle 12 from separating from each other.

[0052] In some embodiments, the first sliding part includes but is not limited to being a cylinder, so that the first sliding part and the side wall of the first sliding groove 111 are in line contact, the contact area is small, the first sliding part moves smoothly along the first sliding groove 111, and the noise generated during the movement is small. Similarly, the second sliding part includes but is not limited to being a cylinder, so that the second sliding part and the side wall of the second sliding groove 121 are in line contact, the contact area is small, the second sliding part moves smoothly along the second sliding groove 121, and the noise generated during the movement is small.

[0053] In some embodiments, the shapes of the first anti-detachment portion and the second anti-detachment portion are independently set. For example, the projection on the surface of the movable plate 13 along the thickness direction of the movable plate 13 includes but is not limited to regular shapes and irregular shapes such as circles, ellipses, and rectangles. The shapes can be flexibly adjusted and set according to actual needs.

[0054] In order to enable the first anti-slip portion to pass through the first sliding groove 111 to realize the disassembly and assembly operation of the movable plate 13 and the first smoke shield 11, for example, the first anti-slip portion includes but is not limited to being set as an elastic portion, and the first anti-slip portion is made to snap into or pass through the first sliding groove 111 by squeezing; for another example, an avoidance portion is formed on the side wall or end of the first sliding groove 111, and the position of the movable plate 13 is adjusted so that the first anti-slip portion is snapped into or passed through the avoidance portion. Similarly, the second anti-slip portion and the second sliding groove 121 can also be set accordingly in a similar manner to the first anti-slip portion and the first sliding groove 111, so that the disassembly and assembly operation of the movable plate 13 and the second smoke shield 12 can be easily realized.

[0055] In some embodiments, a relief recess 1111 is formed on one inner wall of the first sliding groove 111, which is recessed in a direction away from the inner wall of the other opposite side, and the first anti-slip portion can be inserted into or pass through the first sliding groove 111 through the relief recess 1111. In this way, after the movable plate 13 rotates to the position corresponding to the first anti-slip portion and the relief recess 1111, the first anti-slip portion is pushed from the first sliding groove 111 into the relief recess 1111, or from the relief recess 1111 into the first sliding groove 111, so that the movable plate 13 can be removed from the first smoke baffle 11 or the movable plate 13 is connected to the first smoke baffle 11, and the disassembly and assembly operation is more convenient. In addition, a spacing is provided between the relief recess 1111 and the top of the first sliding groove 111, so that when the side wing smoke holding assembly 10 moves to the folded position, the first sliding member 131 is not easy to be separated from the first sliding groove 111, and the operation stability is good.

[0056] In one embodiment, an avoidance hole 1211 is formed at one end of the second sliding groove 121 close to the smoke collecting plate 22, and the second anti-detachment part can be inserted into or passed through the second sliding groove 121 through the avoidance hole 1211. In this way, after the movable plate 13 and the second smoke shielding plate 12 are rotated to the position where the second anti-detachment part corresponds to the avoidance hole 1211, the second anti-detachment part is inserted into the avoidance hole 1211 and moved into the second sliding groove 121 to complete the assembly operation, or the second anti-detachment part is separated from the avoidance hole 1211 for disassembly, and the disassembly operation is relatively convenient.

[0057] See also Figure 3 , Figure 5 and Figure 6 In some embodiments, the top of the first smoke baffle 11 is provided with a flange 112 detachably mounted on the inner wall of the smoke hood 20, and the flange 112 is connected to the inner wall of the smoke hood 20 by connecting members including but not limited to screws, pins, rivets, etc. In this way, the first smoke baffle 11 can be stably mounted inside the range hood.

[0058] See also Figure 3 , Figure 5 and Figure 6 In one embodiment, the side wing smoke collecting assembly 10 further includes a fixing frame 14 and at least one fastener 15 for fixing on the smoke collecting plate 22. The fixing frame 14 is connected to a side portion of the second smoke baffle 12 close to the smoke collecting plate 22 through the fastener 15.

[0059] The fasteners 15 include but are not limited to screws, pins, rivets, clips, etc. The second smoke baffle 12 is provided with mounting holes 122 corresponding to the fasteners 15 .

[0060] In one embodiment, a first avoidance notch 133 for avoiding the fastener 15 is formed on one side of the movable plate 13 close to the smoke collecting plate 22, and a second avoidance notch 113 for avoiding the fastener 15 is formed on one side of the first smoke shield 11 close to the smoke collecting plate 22. In this way, when the wing smoke collecting assembly 10 moves to the folded position, the fastener 15 can be respectively inserted into the first avoidance notch 133 and the second avoidance notch 113, so that the first smoke shield 11, the movable plate 13 and the second smoke shield 12 can be folded together normally, preventing the first smoke shield 11 and the movable plate 13 from interfering with the fastener 15 during movement.

[0061] In some embodiments, the fixing frame 14 includes a fixing plate 141, and the fixing plate 141 is stacked on a side portion of the second smoke baffle plate 12 close to the smoke collecting plate 22. A third avoidance notch 1411 is provided on the fixing plate 141 to avoid the second sliding member 132. In this way, when the side wing smoke collecting assembly 10 moves to the folded position, the anti-detachment portion of the second sliding member 132 can be inserted into the third avoidance notch 1411, so that the first smoke baffle plate 11, the movable plate 13 and the second smoke baffle plate 12 can be folded together normally, preventing the movable plate 13 from interfering with the fixing plate 141 during movement.

[0062] Specifically, there are more than two third avoidance gaps 1411 and more than two second sliding members 132 , and each third avoidance gap 1411 is correspondingly disposed with each second sliding member 132 .

[0063] In one embodiment, a range hood, including but not limited to a side-suction range hood and a 7-shaped range hood, comprises a side wing smoke collecting assembly 10 of any of the above embodiments, and also comprises a smoke collecting hood 20, wherein the side wing smoke collecting assembly 10 is provided in two and is located on opposite sides of the air inlet 21.

[0064] The above-mentioned range hood, when in the folded position, the first smoke baffle 11, all the movable plates 13 and the second smoke baffle 12 are stacked together and are all located inside the smoke hood 20. Stacking together takes up little space and can be adapted to be installed inside the smoke hood 20 in a narrow space; when in the unfolded position, the first smoke baffle 11, all the movable plates 13 and the second smoke baffle 12 are unfolded with each other, which can increase the smoke collection space compared to the method of only setting the second smoke baffle 12 in the related art, thereby improving the smoke collection effect.

[0065] In some embodiments, the range hood further includes a driving mechanism, which includes but is not limited to being disposed inside the smoke collecting hood 20 , and the driving mechanism is connected to the smoke collecting plate 22 , and can drive the smoke collecting plate 22 to open or close.
